Managing Invasive Plants in the Residential Landscape
Invasive plants are one of the most common, and most misunderstood, challenges in residential landscapes. I’ve seen it time and time again: a beautiful house with a wonderful lot, in a great neighborhood, sitting where a forest once stood hundreds of years ago: huge strong old growth trees with native ephemerals carpeting the ground, wildlife, that today would dominate chatter on the next door app. Nature on its own exercised graceful dominion over the wild landscape. Today, we see a different picture, maybe shady deck that looks over a small lawn leads to a natural area with large trees, not old with the gnarled grandeur of their ancestors, but younger and not likely understood by you other humans , those that now claim dominion over it. Those places around our homes will never be the same, the stretches of suburban wood, permanently now changed forever. They have something else new living in them, invasive species. Chances are, this plagues your own landscape or garden and you want to take back control.
Author’s note: For the purpose of this article, I am not talking about common garden, or lawn weeds. I focus on invasive plants that often dominate around houses with large trees (which is candidly) a ton of house in the Carolina piedmont. For location context, I live and work around Raleigh, NC, so I am writing this through that geographical lens but this article hold broader application through principal to other places. -JGR
Chinese wisteria (Wisteria sinensis), English ivy (Hedera helix), Chinese privet (Ligustrum sinense), glossy privet (Ligustrum japonicum), and Elaeagnus species, to name a few, have become defining features of suburban and urban-adjacent land. These plants are aggressive, resilient, and exceptionally good at exploiting disturbed environments.
Why does it seem that our land is dominated by these aggressive bullies from Eurasia and Southeast Asia?
The main problem with invasive plants is not their mere existence. In fact, many of them fit surprisingly well into our altered local ecology. Ligustrum flowers provide nectar for pollinators that are being pushed toward endangerment due to a lack of available floral resources. Birds readily consume privet berries. And English ivy—despite its overaggressive nature—blankets forest floors with photosynthesizing, carbon-sequestering greenery.
The real issue is that invasive plants fill ecological voids that were once occupied by native species. Those native communities were vastly more diverse. Where we may now see three or four dominant plants, there could instead be a beautiful garden with hundreds of species supporting a greater range of life. That kind of abundance still exists in protected places; something you notice immediately when hiking in the places like the Smoky Mountains in spring, where wildflowers, insects, and wildlife are present in staggering diversity. Much of that richness has been replaced in residential and suburban areas by monocultures of invasive plants.
There is a clear relationship between human habitation and the presence of invasives. The farther you get from development, the fewer invasive plants you see. It’s almost as if they know we are there. Our habits of clearing land, building structures, disturbing soil, and planting species we probably shouldn’t, create perfect conditions for invasives to thrive.
The good news is that there are ways to manage these plants and restore your land to a place that either supports biodiversity with very low inputs or hosts your own tangibly abundant forest or garden.
Managing Invasive Vines
If we’re talking about wisteria or English ivy, or Japanese honeysuckle, we’re dealing with climbers. While they grow upward, all of their water and nutrient intake comes from roots anchored firmly in the soil. Here’s the basic math of understanding your enemy to defeat them: the place they are most vulnerable is where the vine meets the ground because that spot is feeding all the growth through the plants vascular system there.
The first and most important step is to cut these vines at the base. Once severed, they will die, slowly decompose, hopefully fall off, and stop strangling the trees and shrubs they’ve been climbing. That still leaves the vines themselves, in the case of English ivy, extensive mats running along the ground.
Ideally, you would pull or dig these plants out completely, but that can be extremely labor-intensive. A more efficient approach is repeated cutting and mowing.
If you cut all the vines climbing trees and shrubs, carefully pull them away from trunks to avoid damage to the trees vascular system (which is often just inside the bark), and then mow or string-trim everything on the ground down to bare soil, it looks like a job well done right? Unfortunately no, the plants will regenerate, and your problem will start all over again. Those invasive vines still have substantial energy reserves in their roots. If you stop there, you’ll be close where you started within a year.
But if you stay on top of it, the outcome changes dramatically.
Imagine cutting everything in May. Then you return in June and mow all regrowth. You do the same in July, August, and again in early fall—never allowing new green leaves from the invasive vines to persist long enough to replenish the plant’s energy reserves. After four or five consecutive knockdowns, those reserves are depleted. The following year, the plants struggle to survive, your job is much easier and another round of mowing and weed eating nearly seals the deal if you are diligent.
This is the most labor-efficient method of controlling invasive vines I have ever found.
There are arguments for herbicide use, but for plants like English ivy with thick, waxy cuticles, spraying requires heavy chemical applications to be effective. In most residential settings, the environmental risk of soil contamination and runoff into streams is simply not worth it.
Managing Woody Invasive Species
When it comes to woody invasives, Bradford pear, privets, Elaeagnus, and other heavy hitters—the strategy shifts slightly.
Digging these plants out by the roots is effective when they’re young, especially privets, which are notoriously weak rooters. But once they’re established, cutting becomes the most practical option.
The key is timing and technique. Cut woody invasives during a warm season—here in North Carolina, roughly mid-March through early fall. When the plant is freshly cut, the vascular cambium is exposed and has not yet sealed.
Many invasive woody species regenerate aggressively through water sprouting and suckering. To prevent this, apply a targeted, biodegradable herbicide directly to the fresh cut surface. Despite its reputation, glyphosate—when used precisely and sparingly in this way—is one of the safest and most effective tools available. (It’s worth noting that some products sold under the Roundup name now contain triclopyr instead.)
If herbicide use isn’t an option, repeated cutting and mowing of resprouts can also exhaust the plant’s energy over time, though it requires more persistence.
Japanese Stiltgrass: A Special Case
We also need to talk about Japanese stiltgrass (Microstegium vimineum).
What makes Japanese stiltgrass especially concerning is that, unlike ivy or privet, it’s an annual—at least here in North Carolina. It doesn’t survive year to year as a plant; it survives through seed production, and it produces a staggering amount of seed.
One small plant can generate hundreds of seeds, which scatter across the soil surface and germinate en masse each spring. That makes it one of the hardest invasive species to control.
The most effective strategy, again, is consistency. Mow or string-trim it relentlessly throughout the growing season. Pulling is effective but labor-intensive. Cutting it down is easier and still works—as long as you prevent it from setting seed. Late-season vigilance is critical. Once those seeds mature, the problem compounds dramatically the following year.
Japanese stiltgrass is an absolute menace. If it’s present in your landscape, it’s worth considering a transition toward planted groundcover or native vegetation that can outcompete it and better serve both you and the environment.
A Balanced Perspective
At the end of the day, I would rather see an invasive plant than no plant at all. Bare, destroyed ground—cleared forests reduced to piles of dirt—is far more damaging to our environment than invasives. In many cases, invasive plants are still participating in ecological processes and supporting some forms of life.
There is no realistic future where invasive plants disappear entirely from residential or suburban landscapes. They are here, and they are successful.
What is realistic is creating space for native habitats to survive—habitats that existed long before invasive plants or European settlement arrived in North America. Invasive plants aren’t evil; they’re simply highly adapted to disturbed land. The problem is that they occupy space that could otherwise support biodiversity we are at real risk of losing forever.
Managing invasive plants isn’t about erasing them from the landscape. It’s about making room, for native ecosystems, for ecological resilience, and for your own garden and landscape that supports food production, looks beautiful, heals your mind and spirit, and provides a little contribution to long-term environmental stability.
